India’s two-wheeler market is witnessing a quiet revolution. With fuel prices fluctuating and environmental concerns rising, manufacturers are looking for alternatives beyond petrol and electric. Hero MotoCorp, India’s largest two-wheeler maker, has taken a bold step forward by launching the Hero HF Deluxe Flex-Fuel 2025, the first 100cc bike in India to support ethanol-blended fuel up to E85.
Designed for the daily Indian rider, the new HF Deluxe Flex is a smart and affordable solution that combines eco-friendliness, performance, and fuel cost savings. Let’s explore what makes this bike unique and why it’s creating buzz in the commuter segment.
🔍 What is Flex-Fuel?
Before we dive into the specs, here’s a quick explanation of flex-fuel:
A flex-fuel vehicle can run on more than one type of fuel. The HF Deluxe Flex is compatible with petrol and ethanol-blended petrol ranging from E20 to E85 (20% to 85% ethanol mixed with petrol). This allows riders to use cheaper, eco-friendly fuel options whenever available.
This is a game-changing move by Hero, aligning with the Indian government’s push toward ethanol-based fuels and reduced carbon emissions.
🛞 Engine and Performance
The 2025 HF Deluxe Flex is powered by the trusted 97.2cc single-cylinder, air-cooled engine, now tuned to support flex-fuel. This engine is the backbone of many Hero commuter bikes and is known for its ruggedness and efficiency.
Key Engine Specs:
- Power Output: 7.9 bhp @ 8,000 rpm
- Torque: 8.05 Nm @ 6,000 rpm
- Gearbox: 4-speed constant mesh
- Starting Options: Self-start + Kick start
Despite being ethanol-compatible, Hero has ensured there’s no compromise on throttle response, low-end torque, or daily performance. Whether you use petrol or ethanol-blended fuel, the bike delivers consistent and smooth rides.
⛽ Mileage and Fuel Efficiency
Mileage is a top priority for Indian riders, especially for those using their bikes for daily commutes, deliveries, or long-distance rural travel.
Estimated Mileage:
- Petrol (E20): 65 to 70 km/l
- Ethanol-blended fuel (E85): 50 to 55 km/l
- Average daily usage cost drops when ethanol is cheaper than petrol
Keep in mind that ethanol is generally cheaper than petrol, which can reduce your monthly fuel expense. Even though ethanol has a slightly lower energy density, the overall running cost is lower, making it ideal for budget-conscious riders.
🌿 Environment-Friendly Commuting
One of the standout features of the HF Deluxe Flex is its contribution to a greener environment.
- Lower carbon emissions
- Reduces dependency on fossil fuels
- Supports Indian agriculture, as ethanol is derived from sugarcane and grains
- Government subsidies may help lower ethanol prices further
For eco-conscious riders, this bike offers a guilt-free way to travel while promoting sustainable fuel alternatives.
🧱 Design and Styling
Hero has made sure the HF Deluxe Flex stands out with its unique styling updates:
- Striking green-themed graphics indicating eco-friendliness
- “Flex Fuel” badging on fuel tank and side panels
- Bright color options including Green-Black and Green-Red combos
- Chrome-finished exhaust shield
- Black alloy wheels and sleek tail section
The bike retains its familiar commuter-friendly silhouette while adding a futuristic, responsible touch through its new color schemes.
🛋️ Comfort and Ride Experience
The HF Deluxe is built for Indian roads and riding conditions. The Flex model offers the same comfortable and durable platform that the base HF Deluxe is known for.
- Long seat with soft cushioning
- Telescopic hydraulic front suspension
- 2-step adjustable rear shock absorbers
- Lightweight (110 kg approx.) makes it easy for all age groups
- Ground clearance of 165 mm – perfect for Indian road bumps
- Ergonomic handlebar and upright riding posture for daily comfort
It’s a bike that older riders, delivery partners, students, and family men can all ride with ease.
🧠 Smart Features and Practical Additions
Though it’s a budget commuter, Hero hasn’t ignored practicality:
- i3S (Idle Start-Stop System) to save fuel at red lights
- Side-stand engine cut-off for added safety
- Tubeless tyres
- Stylish semi-digital instrument cluster (on higher trims)
- Integrated headlamp beam and pass switch
- Maintenance-free battery
These may not sound fancy but are extremely useful in everyday city riding or village usage where reliability matters more than tech.
💰 Price and Affordability
The Hero HF Deluxe Flex 2025 is expected to be priced around ₹65,000 to ₹70,000 (ex-showroom).
Considering it’s a flex-fuel capable bike with Hero’s reputation for low maintenance, it’s a value-for-money investment for any middle-class household, student, or small business owner.
